Optimization of microclimate of premises and increase of gain in live weight of calves with the use of ions and the aromatic oil of lavender

The article presents the results of applying the ions and the aromatic oil of lavender for growing calves. Under the influence of air ions oxygen negative polarity as separately, and integrated their application with the aromatic oil of lavender was a significant decrease in the indoor air relative humidity by 6.49 - 8.10%, the concentration of ammonia - 33.41 - 49. 24 describes %, hydrogen sulfide - 18.26 - 22.62%, carbon dioxide is 0.10 to 0.13%, particulate pollution- 42.88 - of 61.00% and microbial contamination of air - 35.14 - 50.85%. On the background of the use of ions and lavender oil, there was an increase in the blood of experimental animals compared to control counterparts, the number of red blood cells by 5.68 at 6.89%, hemoglobin - by 4.86 to 5.33%, total protein of blood serum - by 3.34% - 5,05%, gamma globulins - 9.8 -15.51% and increase the gain in live weight on 60th day of the experiment by 4.54 - of 6.73%.Higher rates observed in the second experimental group of animals, where air ions was used in combination with aromatic lavender oil.
